Answer:

Hello! Your answer is D: 75.

Step-by-step explanation:

First we need to find the volume of pyramid A in order to solve this problem:

The formula for the pyramid is: V=\frac{1}{3}(B)(h)

Now we plug in the numbers:

V=\frac{1}{3}(81)(4)

V=\frac{1}{3}(324)

V=108in³

Now we divide pyramid B's volume by pyramid A's:

8,100/108 = 75

So the volume pyramid B is 75 times bigger than the volume of pyramid A!

Hope this helps!

2 to the Third power -(30÷5) +9
OLga [1]

Answer:

11

Step-by-step explanation:

2^3-(30/5)+9

First, you divide 30/5 because it is in parentheses and we are following this rule for order of operations:

P- parentheses

E- exponents

M- multiplication

D- division

A- addition

S- subtraction

so 30/5 = 6 and plugged in is:

2^3-(6)+9

Next, we do exponents:

2^3 = 2x2x2 = 8

plugged back in:

8-(6)+9

Now, we do the math from left to right so:

8-6=2

2+9=11

11 is your answer
